Abstract

Possibility of food allowance optimization by using MS Solver tool is analysed in the research. The model is developed by balancing 22 food products and 30 constraints – 8 nutrients and 22 minimum amounts of food products. The new method differs from the applications of linear programming described in the special literature on nutrition science not only with increased nutritional constraints, but also the minimum amount of every product is introduced as constraints, which does not essentially change costs, but provide quality, for example, for tea or coffee it is recommended to define not x≥0, but x≥3. By modifying minimum amounts of tea, coffee, sugar, spices, it is possible to obtain up to 70% economy from the initial rate. Application of the model is approbated in the computer class during practical classes for students of nutrition science.

Overview

Malnutrition in all its forms is closely linked, either directly or indirectly, to major causes of death and disability worldwide. The causes of malnutrition are directly related to inadequate dietary intake as well as disease, but indirectly to many factors, among others household food security, maternal and child care, health services and the environment. While most nutrition interventions are delivered through the health sector, non-health interventions can also be critical. Actions should target the different causes to reach sustainable change, which requires a multisectoral approach.

This document provides a compact of WHO guidance on nutrition interventions targeting the first 1,000 days of life. Focusing on this package of essential nutrition actions (ENA), policy-makers could reduce infant and child mortality, improve physical and mental growth and development, and improve productivity. Part I presents the interventions currently recommended by WHO, summarizes the rationale and the evidence, and describes the actions required to implement them. The document uses a life course approach, from pre-conception throughout the first 2 years of life. Part II provides an analysis of community-based interventions aimed at improving nutrition and indicates how effective interventions can be delivered in an integrated fashion. It shows how the ENAs described in the first part have been implemented in large-scale programmes in various settings, what the outcomes have been, and to examine the evidence for attribution of changes in nutritional outcomes to programme activities.
